Craggy Island Triathlon 2025 will once again start and finish at the North end of the Isle of Kerrera. The new course proved a hit with participants in 2023 and 2024 as did having the improved facilities at the Marina.
Make sure you are booking the correct day below
With a new swim and run course and a slightly altered bike course we will take in all of the sights that the north of island has to offer.
The course will see you swim 600m point-to-point around the pretty Kerrera Marina, before heading off to Gylen Castle at the South end of the Island on the 16km bike course. Once back at the Marina you will head out for a beautiful 8.5km trail run around the North End peninsula with views towards Dunollie Castle.
The races are off-road, and will take you around the islands coast and over the wild hillside terrain with spectacular views across the Firth of Lorne and Sound of Mull.
Each race will provide a warm (well, we can’t promise the water will be warm!) and welcome environment for newbies and triathlon beginners, as well as a tough off-road challenge for those who fancy their chances at the head of the field.
Using the north of the island, means you can get the event foot passenger ferry directly from Oban, avoiding our previous logistical issue with narrow roads, a lack of near-by parking facilities, and people getting to and from the start line.
Not only that, we’re simply able to bring you much better services, and deliver a better event experience.
Kerrera Marina is home to the Waypoint Restaurant and Bar which will be serving up delicious refreshments throughout the event – or even a beer for your supporters – and possibly even you after the race! You’ll find regular toilets, shelter, and hard standing – simple things that bring a little more comfort. Finally, our event date won’t be determined by the tide.
Craggy Island is supporting the new Kerrera School House Community project aiming to restore the islands’ Old School to become the islands first community hub providing a space for islanders to socialise and hold community events for the first time. Head over to Isle of Kerrera (facebook.com) to find out more and see how you can support them.

Areas of our course are on private land, if you choose to recce the course please avoid these areas.
This will be on a combination of landrover and quad tracks and paths, and is a bit hilly (ahem!). There’s nothing wildly extreme, however, this is proper mountain biking in places, not just riding round a lovely grassy field – if you feel the need to walk a bit, no problem, we’d prefer you stay in one piece!. You’ll see most of the island on your travels, and have what must surely be the most scenic triathlon bike course in the world. Amazing.
MTB Course Description – Adult Race
This is going to be interesting. It’s proper off road. In fact, it’s more like a hill-race than the ‘cross country’ you might remember from school. The route will take you across rough trackless boggy and wild hillsides, but you’ll be rewarded with the most incredible views of the island, across to the Isle of Mull. Along the way you’ll visit the Hutchesons monument with stunning views across to Dunollie Castle, before returning to the finish at the ferry slip. You may wish to incorporate a few hills in your training regime……
The Athlete Guide will be published here approximately 2 weeks prior to race day. Please read it as this will answer most if not all of your questions.

This will allow you to rack your bike in transition before heading to registration. The bike racking will be set up and you should rack your bike in the numbered slot that matches your race number.
Ferries will leave from the Oban Times Pier.
You do not need to do anything to board the ferry to Kerrera. To leave the Island, your Race number is your ferry ticket so please keep hold of it and show it before boarding the ferry to return to Oban.

Normal Triathlon Scotland rules will apply – see www.triathlonscotland.org for further details.
We are really hot on no littering. We rely on the goodwill of our landowners, and we just cannot afford for them to be irritated, or the island spoilt by our litter. This specifically includes Gel/Bar wrappers, Banana skins etc. Simple rule: if you’re caught littering, it’s an instant DQ. You’ve been warned (sorry to be heavy, but…. you know!).
Note: no campervans/motorhomes (vans under 6m/Transit van size are ok) are allowed in our car parks.
Here’s some possibilities for local bike hire. Please note: these aren’t recommendations – we’re just trying to help

Water Temperatures vary depending on the weather conditions pre-event but the sea temperature is likely to be around 12-14oC.
You’ll be getting to the island via some chartered private ferries for the short (15mins) trip across Oban bay. These will leave from Oban Times Slipway in Oban. It is most likely that you will travel on one boat, and your bike on another, arriving around the same time. We encourage you to arrive for the earliest ferry this will keep the flow of competitors and boats moving. Please do not turn up late, once the last ferry has left you will not be able to access the island. There will be space for friends and family to come to the island as well. but they will need to pay for a ticket (c. £5 return). They may not be able to catch the same boat as you, but we will get everyone across. Expect a bit of a queue post-race to return to Oban as everyone tries to leave at the same time. View it as a perfect excuse to grab a beer from the Waypoint Bar and relax 🙂
We would recommend a mountain bike for this event, however depending on biker ability you may be able to use a gravel or cross bike. Please read our course guides carefully before choosing a non-mountain bike option .

I’m definitely an aspiring triathlete rather than a hardcore racer. Craggy Island was my third triathlon with my previous race being the Loch Lomond tri back to June 2018. And...
